Largest Chicago style hot dog on Conan O'Brien Show tonight.

Vienna Beef will be featuring the world's largest Chicago style hot dog on the Conan O'Brien Show tonight. This one of a kind mega dog was transported through the city of Chicago earlier today by an extra long semi trailer truck, led by a police escort. The dog was grilled on a specially designed and built charcoal grill, dressed with all the authentic Chicago condiments, and gently nestled into a single bun on site, before being hand presented to Conan.
